Persiculinae : ウィキペディア英語版 | Persiculinae
''Persiculinae'' is a taxonomic subfamily of minute to small predatory sea snails, marine gastropod mollusks. This subfamily includes several species which are micromollusks. The subfamily is sometimes placed in the family Cystiscidae, and is sometimes instead left in the family Marginellidae the margin snails. It is within the clade Neogastropoda. (Note: Gastropod taxonomy has been in flux for more than half a century, and this is especially true currently, because of new research in molecular phylogeny. Because of all the on-going changes, different reliable sources can yield very different classifications.) == Shell description == The shell minute to large, white, uniformly colored, or patterned; spire immersed or low to tall; lip thickened, smooth or lirate; external varix present or absent; siphonal notch present or absent; weak to distinct posterior notch present; columella multiplicate with combined total of 3 to 13 plications plus parietal lirae; internal whorls cystiscid type.
